6 Claims. 1

This invention relates to mountings for telescopes upon guns and the like.

An important object of the invention is toprovide means for detachably mounting a telescope upon a gun in such a way that the'telescope is held against accidental longitudinal and lateral tipping, no matter what may be the position of the gun.

Another important object is to provide a mounting for telescopes upon guns whereby the telescopes may be readily removed by very simple manipulations, without the use of tools, and may be quickly remounted upon the guns by as simple manipulations.

Still another object is to provide a telescope mounting, adopted particularly for guns wherein V-bases are employed in part to secure the telescope against tipping.

Other objects and advantages of the invention will be apparent during the following detailed description of the invention, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing:

Fig. 1 is a side elevation of a portion of a gun supporting a telescope carried by one form of the novel mounting.

Fig. 2 is a top plan of the same, with the telescope removed.

Figs. 3 and 4 are vertical sections substantially on their respective lines of Fig. 2.

Fig. '5is an end elevation of a V-base forming a portion of the novel mounting as viewed in the direction of the arrows 55 of Fig. 2.

Fig. 6 is a side elevation of a portion of a gun differing from that of Fig. 1, with the novel mounting thereon, the latter being adapted to this gun.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention and wherein similar reference char acters designate corresponding parts throughout the several views, the letters A and B designate two types of guns, the letter C a telescope and D and E, two forms of the novel mountings for the telescope C.

For the purpose of illustration, the gun A is shown as the well-known Winchester 7 0 rifle and the gun B as the similarly well-known Springfield rifle.

Both of guns A and B include a receiver 10 with recess 1 I ending in opposite substantially vertical wall surfaces l2 and I 3.

The telescope C is illustrated as of a conventional shape, having a cylindrical barrel l5, forward end l6 and rearward end. I1.

Referring now to the novel mount D, shown particularly in Figs. 1 to 5 inclusive, it will be seen that it comprises a forward V-base 20, a rearward V-base 2|, a forward clamp means 22 for the telescope C, a rearward clamp means 23 for the telescope C, a plunger 24 carried by the means 22 and 23 and spring means 25 associated with the plunger 24 and means 22.

The-forward V-base 20, shown more particularly in Fig. 3, comprises a member, somewhat L-shaped in vertical section, with one portion thereof preferably a plate, from which a lug portion 3| having a V-notch projects upwardly, preferably'intermediate the end of the plate, and from the rear end of which a flange portion 32 extends downwardly. Means to secure the V-base 20 to the receiver l0, may comprise the walls of openings 33 for the reception of the heads and portions of the shanks of screws 34 which shanks extend into the receiver.

It should be noted that the flange portion 32 is constructed and arranged to extend downwardly with its inner face 35 bearing against the wall surface [2 of the receiver recess II, and from its outer; face 36 extends inwardly a recess or opening3l. Preferably, the recess 31 is wedge shaped having a substantially horizontal face and a second face extending upwardly and outwardly, forming an acute angle with the first face.

The rearward V-base 2| shown more particularly in Fig. 5, comprises a member, also somewhat L-shaped in vertical section, with one portion 40 thereof preferably a plate, from which a lug portion 4| having a, V-notch projects upwardly, preferably intermediate the ends of the plate and from the forward end of which plate a flange portion 42 extends downwardly. Carried by the portion 40 is 2. depending bracket 43 provided with suitable openings for the reception of the heads and portions of shanks of screws 44 for securing the V-base 2| to the receiver wall when the bracket 43 engages the wall thereof as is clear in Fig. 1.

Referring to the flange portion 42, it will be seen that it is constructed and arranged to extend downwardly with its inner face 45 bearing against the wall surface l3 of the receiver recess H and from its outer face 46 extends inwardly a recess or opening 41, This recess 41 also opens into the lower edge 48 of the flange portion for a purpose to be subsequently detailed.

As may be seen, particularly in Fig. 2 the forward clamp means 22 for the telescope C may comprise a pair of arcuate arms providing a split ring portion 50 carried by a base portion 5i and having a conventional screw 52 to draw the sections of the split ring portion together. The base portion 5l not only provides support for the upwardly extending arcuate sections of the split ring portion 50 but it also contains a socket 53 opening into its rearward end face 54 and carries a forwardly-extending lug or bolt 55 projecting from its forward end face 56. This bolt 55 is constructed and arranged to slide into and out of the recess or s1ot'3'l. The rearward'iclampmeans 23, shown particularly in Fig. 4 forthe telescope C may also comprise a split ring portion 60*, like the portion 50, carried by a base portion BI and having a conventional screw 62 to :draw the sections of the split ring portions together, as is well known, to detachably secure the telescope t'o the mount D. This base portion 16! has -,a bore 62 to receive the plunger 24 next to be described.

The plunger 2t carried by the clamp meanszifi and 23 just described, is preferably a length of rigidsuit able material circular in transverse press section, with its forward end section {.65 iconstructed .and arranged to slide into and -goutof the soeket 53 and its rearwardeendsection 5,6 con.- struotedand arranged to slide into and goutpfsthe recess-41. Obviously because of the-shapeof the recess 4-! it may slide into andout of this recess either by a horizontal or a verticahgliding-momee he p un e 24 also d ly e tend intermediate its ends, through the ibQIG {62.

As may be seen by full and dotted l-ines in Fig. :1 and by iull lines in Fig. 3, "the plunger -24 s n no ma l t e o t e socke 53 e the .-full depth: of the socket. ill-he distance may va y b t q a e d t e p n e anust be or y s a ed m th b 1 t s ck t 53 a distance slightly more than the extent the bolt 55 projects into the -recess-3='l. i v

Intermediate .its length, theplungergzll is pro.- vided with an abutment or stop means. llhis may be. an enlargement .61 WhiQhyTiS disppsed along the1plunger=24 between the two baseiportions 54: and 6;! v of the clamp means fland r23;

T p in m 2. may et a x ansion f iq s r n dis q ed n he-p u e 42 it rt on 5 -an t rwar nd b arin t a se ntfi li i us i nrinstcndsto nr e th plun 12 earward land th -c am ineans niorwardly. It-does not-affect the clamp means 23. a

Aside from a diiferent rearward Al -base, the mounting :E of Fig. 6 is substantially dike that of -mounting -D, and similar reierence characters are employedito designate corresponding parts of bothmountings. Y

The rearward v-base JD of the mounting. 12:, comprises amember, somewhat L- shape'dfin -vertical .section, with one portion .H thereof. preferablya plate, from which .lug iportionflz having. a V-notch projects. upwardly, preferably intermediate the ends of the plate and from the for ward end of which plate a, flange portion 1:3 extends downwardly. .Any suitable means rnay be employed toisecure they-base 10 L110 therecei-ver I.l ,:sucl1 as screws.

The flange portion 13 likethe flange portion 42, hasarearward face M wbearing against thesurface 13 .of the recess IFI and a forwar'dpr outer face Elf-110m which extends inWardlya-recesspr slot 16 like the slot--48 and which also opens downwardly in a manner-similar to that of the latter. Inlfact, the only .difi'erence is that the \/--'base Ill does not carry the bracket ,43 of .the V.-.base2'l warden i ea in eain t t eiia e 5 1: e ba The clamp means 22 and 23 are attached to the telescope C as is obvious and spaced apart so that the rearward clamp means 23 is normally spaced rearwardly from the enlargement 6'! a distance sufficient to permit th spring to expand with out having the enlargement abut the means 23.

After the two clamp means 22 and 23 are secured to the telescope C, the rearward end section 66 of the plunger is slid into the recess 1, with the plunger tilted 'withfits forward end s'li'ghtly upwardly. Next, the 'telescope'C is pulled slightly rearwardly which causes the clamp means 22 to move rearwardly and, consequently, the bolt '55- willlberetracted so that it can enter the recess 3! when the plunger and telescope are in parallelismt with the bases of the V-notches, since what is desired is that the cylindrical barrel l5 of the telescope be in good frictional contact with the walls-of ithese notches.

With the arrangement disclosed the telescope cannot tipJaterall-y [and it -is:.also retainedagainst accidental tipping longitudinally.

It is now clear that thespecific shape of the belt urged .forwardly (by the spring .means- '25 tends to ,pull the telescope into .firm contact with the walls-of the--v-no.tch of thewforward V-base, yet lthesrear end vportion of the telescope cannot tilt upwardly so long as the rear end portionofthe plunger -is--within :the recessA-l.

When :it-is-desired rte-remove the telescope C, all thati-s needed :is to draw the telescope rearwardly, tipthe Jiorward-end until the -bolt '55 clears the forward v-base 20 and then carry the telescope slightly forwardly. r l

Various changes may be made to .thefiorms ol theinventionlherein shown =and-described without departing fromrthe spirit of the invention or scope of the claims.
